Anglo-Saxon Rune Poem (from ragweedforge.com)
Peorth is a source of recreation and amusement to the great,
where warriors sit blithely together in the banqueting-hall
Peorth, the rune of chance and luck, marks today. Chance can take many forms, from the easily recognized games to chance, to anything that is a risk, a leap of faith, a blind groping in the dark, by which something fortunate is sought. As one of the parts of the whole weaving which can be considered part of wyrd and orlog, it is the one most sought after and often praised, at least when it is unfortunate. But usually when misfortune is met with, fate or the evil conspiracies are usually blamed as the culprit, now matter how unlikely it maybe.
